1. for the carnival, the park rented a dunking booth shaped as a rectangular prism. the booth is 3 1/2 ft wide, 3 1/2 ft long, and 8 ft tall. (a) what is the total volume of the dunking booth? (b) if they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Part a) The total volume is

Part b)

Step-by-step explanation:

Part a)

Find the total volume

we know that

The volume of a rectangular prism is equal to

we have

substitute in the formula

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Multiply the total volume by 6/7

so

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
